Refactor easter egg functionality, fetch strings from JSON

- Refactored the `initEasterEgg` function to fetch easter egg strings from a JSON file instead of hardcoding them.
- Removed the unused `eastereggstrings` array.
- Updated event listener to use arrow function syntax (`evt`) instead of `event`.
- Added error handling for failed fetch requests.
